delivered tbe opinion of tbe court:
Paragraph 44 of tbe tariff act of 1913 reads in part as follows:
44. * * * Wool grease, including that known commercially as degras or brown wool grease,' crude and not refined or improved in value or condition, one-foorth cent per pound; refined or improved in value or condition, and not specially provided for in this section, one-half cent per pound; lanolin, 1 cent per pound. * * * ...
Two varieties of products of wool grease are known, respectively, as “adeps lanse anhydrous” and “adeps lanse cum aqua.” Both are conceded to fall within tbe phrase “wool grease * * * refined or improved in value or condition” as used in tbe aforesaid paragraph. It being conceded that the term “lanolin” as therein used is more specific than the phraseology last referred to, and that the' adeps lanse cum aqua falls and is included therewithal, and dutiable thereunder, the question presented and controverted in. this appeal is whether or not the adeps lanse anhydrous product of wool grease also falls therewithin and is dutiable as “lanolin.” The Board of General Appraisers held that it did not so fall and was not so dutiable. The Government appeals. While, both products were involved in the decision of the board, the importers, who are- appellees here, concede that the adeps lanse cum aqua is included within the term lanolin and is not, therefore, properly dutiable under the phrase wool grease refined or improved in value or condition. In other words, the Government claims both the products are dutiable as lanolin, whereas the importers admit the adeps lanse cum aqua to be, but deny that the adeps lanse anhydrous is so dutiable, claiming that product dutiable as “wool grease * * * refined or improved in value or condition” under the same paragraph. There was no testimony upon this point introduced before the board, their decision being predicated upon the definition of “lanolin” as given in certain *173scientific treatises, which, it was hold byy-the board conformed with the lexicographic definitions of lanolin. On the other hand, the Government maintains, among other matters urged, that “'lanolin” as commonly used and understood includes both these products, and that the board erred (1) in resorting to and (2) in adopting the scientific definitions in the publications in question in order to determine and in determining the issue presented.
At the threshold of the inquiry the Government presents the proposition, generally, that resort to scientific definitions and publications in the determination of tariff issues is error.
In consideration of this question it may be well to observe primarily the distinction which is pointed out by the authorities between receiving in evidence scientific publications and the consultation of them by the court as aids in refreshing the memory as to scientific facts, truths, and laws.
In this case the error assigned is, first,- .that the articles patent issued some years since by the Patent .Office of- the United States for an article therein denominated as “lanolin” or “lanoline” were improperly admitted. It is the view of the court that this was not error. -
It appearing from the record that the origin of the word “lanolin” was marked by the issuance of these letters patent, whereby a new term was introduced into the language of the country, the letters patent were, at least, admissible for the purpose of showing the origin and in part the history and development of the term which the court is here called upon -to interpret. Furthermore, the rule is universal that a court in order to refresh its memory may resort to public documents and records. The principle is concisely stated in 16 Cyc., 922, as follows: ’
The judge may resort to or obtain information from any source of knowledge which he feels would be helpful to him, including public official documents of all hinds, whether of the State or National Government—such as those in the State or Navy Departments, Census Bureau, or Land Office. Indeed, he may resort to any public document properly authenticated. [Italics ours.} (For citations supporting text see volume and page quoted.) • . .
■ It is well settled that the records of the executive departments of the Federal Government aré public records and within the judicial cognizance of th,e courts. The rule was applied as to the Department of the Interior, within which is included the Patent Office, from which the letters patent here admitted emanate, in Knight v. United States Land Association (142 U. S., 161, 169). See also Gardner v. Collector (6 Wall., 73 U. S., 499, 509), Armstrong v. United States (13 Wall., 80 U. S., 154), Coffee v. Groover (123 U. S., 1, 11), New York Indians v. United States (170 U. S., 1, 32), Jones v. United States (137 U. S., 202), Duncan v. Navassa Phosphate *174Co. (137 U. S., 647), Paquete Habana (175 U. S., 677, 712), ex parte Hitz (111 U. S., 766), In re Baiz (135 U. S., 403, 432).
The particular sources of information, adverted, to by the board were Chemical Technology and Analysis of Oils, Fats, and Waxes (1914); by Lewkowitsch, Encyclopaedia Britannica (1911), United States Dispensatory (1907), U-nited States Pharmacopoeia (1905), and New and Nonoflicial Remedies, published by the .American Medical Association (1912). These are either chemical treatises or chemical definitions from standard works. It requires neither argument nor authority to support the fact that chemistry is one of the 'well-recognized sciences, that treatises upon that subject -are scientific treatises, and definitions thereof scientific definitions.
A broad, general rule as to what.the court may advert to in order to refresh its mind, as distinguished from wfiat may be introduced in’evidence in a case, is set forth in 16 Cyc., 922, part of which was quoted hereinbefore, as follows:
This power of the court is not only valuable in shortening trials of fact, but it is useful to an appellate court by preventing reversals where the evidence on the recoi d fails to establish a result which is in accordance with substantial justice. The judfje may resor^to or obtain information from any source of knowledge which he feels would be helpful to him, including public official documents of all kinds, whether of (he State or National Government, such as those in 'the State or Navy Departments, 'Census Bureau, or Land Office. Indeed, he may resort to any public document properly authenticated; to dictionaries, hoolcs, periodicals, and public addresses. He may even inquire of others. On matters of public history he may examine public documents, histories, or other writings of historical data. He may inform himself as to the facts of geography, .such as the navigable character of a river, the distance between two points,, the location of a given place within the jurisdiction, by resort to histories, geographies, public documents, maps, etc. Where the court is authorized to construe, or to charge the jury concerning the ordinary meaning of words in the vernacular, th’e judge may resort to dictionaries, works of history, or other writings, which while not strictly evidence, but merely serving to bring actual up to judicial knowledge, or aiding, as the Supreme Court of the United States say, “the memory and understanding of the court.” [Italics ours.] (For- citations supporting text see volume and page quoted).
Tne sources of information may include matters of public notoriety within the court’s memory (United States v. Whitridge, 197 U. S., 135), or matters of science as recorded in scientific works (Brown et al. v Piper, 91 U. S., 37, 42; Hoyt v. Russell, 117 U. S., 401, 405), or history and historical works (Hoyt v. Russell, supra), or dictionaries (Nix v. Hedden, 149 U. S., 304, 307).
Some specific decisions may well be adverted to. Thus in Union Pacific Railway Co. et al. v. Yates (79 Fed., 584, 588), relied upon by the Government herein, it is said:
All the authorities agree, we believe, that standard works which deal with the exact sciences, including herein interest and annuity tables, and tables compiled from well-established data showing the average duration of human life,, are receivable in evidence to establish the facts to which they relate. Schell v. Plumb (55 N. Y., *175698), Mills v. Catlin (22 Vt., 98), Munshower v. State (55 Md., 11), Green v. Cornwell (1 City H. Rec., 11). We can perceive no reason why the truths of exact science to which all intelligent persons assent, and well-established historical facts, should not be proven by the writings of competent authors, and all courts agree that they may be so proven. [Italics ours.]
It will be observed that tbe court therein was speaking not alone of what the court might resort to -judicially but of what might be actually introduced as evidence in the case. So in Jones v. United States (137 U. S., 202, 216), Mr. Justice Gray, speaking for the Supreme Court, said:
In the ascertainment of any facts of which they are bound to take judicial notice, as in the decision of matters of law which it is their office to know, the judges' may refresh their memory and inform their conscience from such sources as they deem most trustworthy. (Gresley Eq. Ev., pt. 3, c. 1; Fremont v. United States, 17 How., 542, 557; Brown v. Piper, 91 U. S., 37, 42; State v. Wagner, 61 Maine, 178.) [Italics ours.]
And in Brown et al. v. Piper (91 U. S., 37, 42), á case often referred to upon this subject, Mr: Justice Swayne, speaking for the court, said:'
Courts will take notice of whatever is generally known within the limits of their jurisdiction; and, if the judge’s memory ;s at fault, he may refresh it by resorting to any means for that purpose which he may deem safe and proper. This extends to such matters of science as are involved in the cases brought before him. [Italics ours.]
In Kaolatype Engraving Co. v. Hoke (30 Fed., 444, 446), Judge Thayer, after reciting certain dictionaries, said:
• As the case has been presented, the question really before us is whether we will take judicial notice of certain processes described in various mechanical dictionaries, encyclopedias, and other publications produced on the hearing of the demurrer, and, by reason of our taking judicial recognizance of such processes, determine that the patent in question does not describe an advance in the art to which it appertains rising to the dignity, of an invention. Besides those facts of which courts are bound by law to take judicial notice, they will ordinarily only take notice of facts of universal notoriety—of facts that are so generally understood that they may he regarded as forming part of the common knowledge of every person. Brown v. Piper, supra. The matters of which we are asked to take judicial cognizance in this instance, and thereupon declare the invalidity of this patent, do not strike us as falling within the last category. They are a class of facts which might more properly be called, to our attention on the hearing (with opportunity to the other side to rebut or explain) as tending to show the state of the art to which this patent appertains, and for the purpose of enabling us to determine whether this patent really describes a newly discovered process which called for an exercise of the inventive faculty. [Italics ours.].
The question seems concluded -in this court in the case of Rotograph Co. v. United States (1 Ct. Cust. Appls., 82, 85; T. D. 31106) wherein the court said:
. . Reference to works of this character may be had-for the purpose of showing the state of the art. See Brown v. Piper (91 U. S., 37, 40); Nix v. Hedden (149 U. S., 304, 306). In the latter case it was held that the court would take judicial notice of the ordinary" meaning of words, and upon such a question dictionaries are admitted, not as evidence, but as aids to the memory and understanding of the court.' It was said by Mr. Justice Swayne, in Brown v. Piper (supra): “Courts will take notice of whatever is generally *176known within the limits of their jurisdiction; and if the judge’s memory is at fault he may refresh it by resorting to any means for that purpose which he may deem safe and proper. This extends to such matters of science as are involved in the cases brought before him.” [Italics ours.]
The clearly deducible rule from authorities, therefore, seems to be, that a court is warranted, that the ends of justice may not be defeated', in taking judicial notice of such public records, documents, dictionaries, and scientific treatises which the court, under all the circumstances of the case “may deem safe and proper.”
It may be appropriate to remark that this conclusion perfectly accords with the practice of all courts, tribunals, and officials interpreting customs laws since the foundation of the Government and that the adoption of any other rule discards the selected and approved wisdom of both the ages and modern years, which, uniformly, it may be said, in deference to public criticism and-rejection and in the interests of acceptance and approval, keeps abreast with the advance in mechanism, science, and the arts, and, in lieu thereof, would probably make such courts, tribunals, and officials controlled in their decisions by the limited knowledge of the interested and too frequently uninformed vendor of the particular merchandise.
Wherefore the court is of the opinion that in this case the board was entirely, justified in its examination of the authorities noted and the refreshing of its memory therefrom.
An examination of those authorities we think clearly draws a distinction between adeps lanse anhydrous and adeps lanse cum aqua in 'that they class and admit the latter and not the former as lanolin. The question then presented is whether or not this scientific definition or classification of the term accords with or is contrary to its common acceptation which as spoken is set forth in its various lexicographic definitions. Of course, the rule is well established that if the latter were the case the common acceptation must prevail in import customs revenue adjudication.
Thus, in Lutz v. Magone (153 U. S., 105), the court said:
It is entirely well settled, however, that in the interpretation of the revenue laws words are to be taken in their commonly received and popular sense, or according to their commercial designation, if that differs from the ordinary understanding of.the word. Customs officers are presumed to be acquainted with the ordinary meaning of words, and may also be presumed to have some familiarity with trade, designations and the ’ customs of dealers. They are not, however, supposed to be chemists, scientists, or professional men, nor to be conversant with the terms of particular arts. [Italics ours.]
So the Supreme Court, in Two Hundred Chests of Tea (9 Wheat., 22 U. S., 430, 438), said:
Whether a particular article were designated by one name or another, in the country of its origin, or whether it were a simple or mixed substance was of no importance in the view of the legislature. It did not suppose our merchants to be naturalists, or geologists, or botanists. It applied its attention to the description of articles, as they derived their appellations in our own markets, in our domestic as well as our foreign traffic.
*177See also Merchants’ Despatch Transportation Co. v. United States (121 Fed., 443), wherein the court applied the common acceptation of the term “albumen” as against the technical chemical understanding thereof; Nordlinger v. United States (127 Fed., 683; T. D. 24976); United States v. Buffalo Natural Gas Fuel Co. (78 Fed., 110).
The common or general acceptation of the term is, of course, evidenced by the lexicographic uses of the word.
While some of the lexicographers, notably in the New Standard Dictionary, Webster’s International Dictionary, and the Century Dictionary and Cyclopedia, adopt definitions of ‘ Tanolin ” broad enough to include articles other than adeps lanas cum aqua, that does not appear to be the commonly accepted use of the term as shown by other authorities of common speech. We quote:
The New International Encyclopedia:
Lanolin * * * or adeps lause hydrosus.'—The purified fat of the wool of the sheep, mixed with not more than 30 per cent of water. It is a white fatty substance, insoluble in water, not subject to decomposition, and not irritating to the skin. It is used as an emollient, and also as a base for various ointments.
Encyclopaedia Britannica (eleventh edition):
Lanolin.—* * * The commercial name of the preparation styled adeps lanse hydrosus in the British Pharmacopoeia, and which .consists of 7 ounces of neutral wool-fat (adeps lanse) mixed with 3 fluid ounces of water.
Wherefore it is obvious that the term has no commonly understood meaning contrary to its scientific acceptation as shown by this record.
Affirmed.
